CLAMP FOR ROPE HALTERS.

SPECIFICATION forming part of Letters Patent No. 315,614, dated April14, 1885.

Application filed November 3, 1884. (No model.)

To all whom it may concern.-

Be it known that I, THoMAs HALL, ofAuburndale, in the county ofMiddlesex and Commonwealth of Massachusetts, have invented a new anduseful Glanip for Rope Halters, of which the following is aspecification.

My invention relates to rope halters as generally used in stables, theobject of it being to provide a convenient and reliable means ofsecuring the rope of ahalter; and it consists of the devices hereinafterdescribed.

Rope halters as heretofore used have been tied into a ring or a holein aplank or around a stanchion or stud. Horses frequently acquire a habitof untying such a knot made in a rope and freeing themselves from therestraint 0! a halter. By the use of my clamp this is 1 cnderedimpossible.

This clamp is made of any suitable metal, iron being as good as any,cast in two parts, which are circular in form,- and are united by astrong screw, on which the clamp is opened and closed, which I willdesignate as the workingscrew.

In the drawings annexed, Figure 1 shows the clamp in perspective asaflixed by screws to a plank forming the side of astall or manger, withthe halter-rope secured in it between the two parts. Fig. 2 shows avertical section of the clamp through its center when closed and holdingthe rope of a halter, and a side of the working-screw.

a is what I will designate as the bed-plate of'the clamp, circular inform,with holes near its edge, through which screws are entered into theplank to which it is affixed to secure it in place. The upper or outersurface of this bed-plate has a groove in it for the rope of the halterto be in, running around it parallel to the periphery of the bedplate,corrugated in the bottom, and with a part of the rise of the outside ofthe groove cutaway on one side to make a place for the fold of the rope.In the middle of the upper side of the bed-plate a conical stud aboutthreequarters of an inch in diameter rises about threequarters of aninch, through the center of which from the under side of the bed-platethere is made an opening for the passage of the workingscrew, withscrew-threads cut in it, in which the threads of the working-screw move.

a is the hollow screw-threaded cone-stud on the bed-plate.

a" I call the closing-disk of the clamp,consisting of a fiat circularplate about one-quarter of an inch thick, the diameter of which is aboutthree-quarters of that of the bedplate, having connected to its upperside by a neck of metal a knob, by which it is turned either way.

a is the knob on the closing-disk, and (ii is the neck by which it andthe disk are united and made integral, in the center of which is acavity, into which the conical stud on the bed-plate enters when theclamp is closed to secure the rope.

a is the working-screw. This screw is about one-half of an inch indiameter, made of steel or good tough wrought-iron, with a thread out onit, which fits the thread in the opening through the bed-plate in thecenter of the conical stud, and a head on'it below the under side of thebedplate, the opposite end of it being firmly secured in the bottom ofthe cav ,ity in the neck a a is the halter-rope.

By turning the knob a to the right it and the closingdisk c are by themoving of the working-screw carried down toward the bedplate upon thehalter-rope, engaging and securing it, so that it will be firmly helduntil released by turning the knob a? to the left.

Having thus described my inventionfl claim as new-- The above-describedhalter-clamp, consisting of the bed-plate a, having on it the hollowscrew-threaded conestud c,the closing-disk a, having on it and integralwith it the knob a and connecting-neck a", and the working-screw a allin combination substantially as described.
